CUSTOM-BUILT MULTIGENERATIONAL HOME WITH OWNED SOLAR, TESLA POWERWALLS & PANORAMIC MOUNTAIN VIEWS Designed with exceptional attention to space, function and long-term livability, this custom-built single-level home at 10401 E Plumeria Rd offers a rare combination of multigenerational flexibility, energy-efficient systems, oversized living spaces and beautiful high-desert surroundings. The home was thoughtfully designed by the owner to accommodate multiple living arrangements, including dedicated areas for extended family, guests or live-in care. Its expansive split floor plan provides separation and privacy while maintaining comfortable shared living and gathering spaces. ENERGY INDEPENDENCE A major feature of the property is its fully owned, net-metered solar system, paired with two Tesla Powerwall battery storage units and an integrated standby generator. According to the seller, the system has historically generated TEP rate credits and substantially offset the home's electrical costs. Battery storage and generator backup add another layer of energy security during outages or grid disruptions. EXPANSIVE INTERIOR LIVING At the center of the home is a spacious kitchen with abundant counter space, a large pantry and sunny breakfast nook. The kitchen flows naturally into the formal dining area and expansive great room, creating an inviting setting for everyday living and entertaining. The light-filled great room features high ceilings and views of the surrounding desert landscape. A remarkable 33' x 13' glass-enclosed Arizona Room extends the living space and offers flexibility as a year-round indoor/outdoor retreat, exercise area, game room, hobby space or additional gathering area. One of the home's most distinctive features is its impressive 23' x 31' private library. With exceptional scale and flexibility, the room could also serve as a media room, creative studio, collection space or specialized home office. A separate executive office provides a quiet workspace with panoramic views toward the Catalina and Rincon Mountains and the surrounding Sonoran Desert. MULTIGENERATIONAL & FLEXIBLE DESIGN The split-wing floor plan includes exceptionally spacious bedroom suites with private bathrooms and walk-in closets. The layout offers excellent flexibility for extended family, long-term guests, caregivers or households seeking greater separation between living areas.
